The PID control is most widely applied, and has the advantages of simple principle, easy realization, wide application range, direct and effective performance and the like. However, when facing some systems with certain requirements on control accuracy, the PID method has a general control effect; fuzzy logic control is to make a fuzzy table by professionals, to carry out table look-up reasoning on different states of the system to infer corresponding control strategies, which is very suitable for systems only working in certain specific states, but has the defect that the making of a good fuzzy table generally needs to be obtained by professional technicians through experience accumulation and continuous tests of long-time field operation; the neural network control is an emerging intelligent control method in recent years, has good adaptability and good control quality for a nonlinear time-varying system, a time-delay system and a complex system which is difficult to model, and has the defects that a large amount of data needs to be subjected to real-time operation processing, a processor has higher performance requirements, the development difficulty is higher, and a large amount of actual data training is needed.
The single neuron PID controller is based on a PID controller, and combines adaptability of neural network control and self-learning property thereof, a better control effect can be generated when a system with an unknown system model is controlled than when the system is controlled by using the PID controller alone, which is proved in recent literatures, a Hebb learning rule is generally used for a learning rule of the single neuron PID controller, a proper learning rule needs to be selected according to the system property in the aspect of rule selection, but a better effect can be achieved in the learning mode by selecting the single neuron PID control learning rule, and no related literature is explored in the aspect at present.
